This can be done by breaking say 1500 ft Beverage into 3 segments with two
relays inserted at 500 and 1000 ft points, switching between next wire segment
and termination resistance.
Some pictures of W8LRL installation are at

white posts support phased and staggered Beverages. Also pictures of RX
vertical 8 array.
